MEDICAL PUMP.

SPECIFICATION forming part Of Letter Patint N0. 634,678, dated October10, 1899.

Application filed Hay 26, 1899. :Serial No. 718,342. (No model To allwhom t may concern.-

Beitknown that I, REINHOLD HWAPPL'EB., a citizen of the United States,residing inthe city and State of New York, have invented an Improvementin Medical Pumps, of which the following is a specification.

This invention relates to an oscillating pump, preferably driven by anelectric motor,

land in connection AWith the cylinder and piston there is a movablevalve-plate with tubu-- lar nipple-handles and e'xible connections Abywhich an alternation of pressure and suction can be applied to Aanyportion of the body, and the action can be) changed by moving the valve-plate Without changing the tubular connections to theparts treated.

By the present improvement an alternation of pressure and suction or acontinued pressurevor suction can be applied by the flexible tubularconnections to any'part of the body. This is available in treatingcatarrhbyatmospheric action or by the injection of medicinal substancesor vapors or the Withdrawal of elete matter, and in cases of deafnessthe apparatus can be used. for energizing the parts of the ear by analternation of pressure and suction or by the injection into thev ear ofany medicinal materialor the Withdrawal from the ear of substances thatmay have been inserted.k A spray can also be employed by this apparatus,ory atmosphere charged with vapor can be projected into or against theaffected parts. j f

This improvement isalso available for massage treatment, in whichalternation of pressure and suction, similar to cupping, can be employedor a continuous suction made use of or acontinuous pressure, and thismay be j used in cases of rheumatism or in thetreat-V ment of boils,abscesses, or other abnormal conditions of the parts or tissues.

In the drawings, Figure 1 is an elevation of the apparatus endwise ofthe armature. Fig. 2 represents the face of the valve-plate. Fig. 3 is aplan view illustrating one end `of the motor and a section ofthecair-cylinder and adjacent parts, and Fig. 4 shows the face of theplate against which the oscillating cylinder. rests.

The shaft Aris revolved by suitable power. I have represented the sameas the arma-ture- `shaft in an 'electric motor A', and this is mountedupon a base B, which may contain a rheostat B3, by which the force of.the current and the speed ot rotation can be regulated, and at Careconductors tothe source Aof electric energy, and, if desired, conductorsD may be led away from one head of the electric motor for use in anydesired manner in'applying an electric current to the body through atransformer B' or by directaction or to a cauterizer or other surgicalappliance, 'the apparatus being made with reference to t the electricalor pneumatic appliances known or used in medical or surgical operations.My said improvem ent,vho\vever, relates to the pump land applianceshereinafter. described. The cylinder E is mounted on the pivot ortrunnion at 3, so that it can oscillate by the action of the piston-rodFto the crank G upon the shaft A, which is rotated electrically orotherwise at the desired speed, and as it ro tates the piston-rod andpiston arerecipro-V cated and the cylinder E oscillatedupon itsdtruunion or pivot.

It is advantageous to employa piston F sufficiently long to oscillatethe cylinder, as thepiston and piston-rod receive their motion from thecrank. The plate 4 is connected to the cylinder E andlies against thexed plate 5 on the face thereof, and the trunnion 3 of the plate 4passes through the plate 5 and through an oblong hole in the valve-plateH on the back of the plate 5, and a spring 2O around the end of thetrunnion 3 presses the plates 4; and H together and to opposite sides ofthe to 5 by screw 6.

fixed plate 5, the plate H being pivoted A scrert7 in the end of thetrunnion Y3 applies tension to the spring 20.

There is a passage-Way or port 13l from the cylinder E through the sameandthe plate 4 to the surface of the plate 4, and in the fixed plate 5there are tivo holes 12 and 14 and on the rear of this plate a slightprojection. YVith the movement of the piston theport 13 moves betweenthe ports 12 and 14, agreeing therewith in its respective positions.

Y The valve-plate H, pivoted at 6, is provided with two nipples 7 and 8,that are adapted to receive the iiexible tubes I K. In this valvel plateH are three small holes 15 to fit over a projection on the rear off theplate 5, which holes determine the several positions of the valve-plateII and hold the same. Through this valve-plate II is a hole S), and intothe same an elongated hole ll and a hole 10, the holes ll and l0 meetingthe holes extending through and from the nipples 7 and S, and theelongated hole ll is ot' sufficient size to cover thev holes l2 and lioi' the plate 5.

There are three positions forthe valve-plate II in relation to the fixedplate 5, and Figs. l and 2 show the first position, in which the holesl0 and 14; agree and l1 and l2 agree. In this position the air is drawnthrough the vessel L and tube I and forced outby the tube K. In thesecond position of the valveplate H the elongated opening ll covers bothopenings l2 and la, and in the movement of the piston and plate 4 thereis alternate suction and pressure through the tube K and other parts areunaffected. In the third position of the valve-plate vII the opening llagrees with the hole let and the hole l2 with the hole 9 throughthevalve-plate, and in this position there is a continuous suctionaction through the pipe K and nipple 8. rection of rotation is reversedwith the parts in the first position, as shown, then the airis drawn inbythe tube K and forced out through the tube I as the pistonreciprocates and the cylinder oscillates.

I have represented a jar L for containing a medicated liquid connectedto the tube l, so that atmosphere can be drawnthrough such liquid intothe cylinder E and then expelled by the tube K to the place Where it isymade use of inedicinally,and by swinging the valveplate I-I in onedirection or the other the action can be changed, so as to produce -analternate suction and expulsion of air through the tube K.

I do, not limit myself to any particular power made use of for rotatingthe crankshaft; but it is generally advantageous to employ the rheostatat B3, so that the speed of rotation can be regulated according to thecurrent and the apparatus can be made use of in medical or surgicaloperations generally.

Any desired provision may be made for lubricating the parts, and a screwis provided at 16 upon the cylinder-head that may be turned to allowmore or less air to pass into and out of the cylinder, and thereby thepneumatic action through the tubes I K will be regulated.

I claim as my inventionl. The combination with an oscillating cylinder,piston, piston-rod and crank, of a stationary plate upon which thecylinder is pivoted, ports through the said plate, a valveplate andpivot and tubes through the same and tubular nipples for the receptionof 'tubular connections, said valve-plate being pivoted so as to bechanged in position to regulate the suction or compression actionthrough the respective tubes, substantially as set forth.
